Reid moved to North London in an £8m double deal with Michael Dawson in January 2005 and initially made the bigger impact at White Hart Lane.
However, while Dawson has established himself as a regular in the Spurs side this season, Reid has fallen down the pecking order and spent much of the campaign in the reserves.
The 23-year-old Irish international has not made a Premiership start since January and looks to be on the move at the end of the campaign.
